Abstract - Seismic analysis of structural systems has been
a necessary in the recent past. The diagrids have favourable circumstances like light weight structure, compelling against gravity stack, resistance against seismic and wind loads, excess, possible for contorted and other complex structures, reasonable. The diagrid structures utilized 33% less steel than common structures with same basic execution. Modelling of the structures with three distinct arrangements for the three diverse story statures independently. To increment the auxiliary execution of the structures by outside segments with the inclining diagrid module for each one of the models. To study and analyze the horizontal relocations and sidelong floats of the all the diagrid models for seismic stacking. To look at the base shear qualities of the models with diagrid individuals. To analyze the above parameters of both diagrid structures and structures with shear divider with seismic stacking. In the current study, models were prepared for G+18 The basic goal of the venture was to concentrate the conduct of the tall structures with the diagrid frameworks and the real horizontal load opposing some portion of the structure. Consequently, three states of the arrangements were considered they are square, octagon and round about. All the three models are symmetric in plan. For each shape three story statures are displayed that is 18 stories, from the past explores it was found the ideal plot for diagrid is around 70 degrees. Utilizing dis information we have displayed the diagrid with an edge of 69.67 degrees. Both the diagrid and shear divider framework models with not have any segments at the building limit. The models were subjected to both seismic and dynamic loads. The structural responses like natural periods, base shear, displacement, Storey Stiffness and inter storey drifts were also studied and located in seismic zone 4 in accordance with IS 1893-2002. From the seismic performance results shows that of diagrid system with shear wall system it is found that the above parameters in diagrid models are much lesser than the shear wall models. Key Words: Diagrid, Column, beam, slab, Shear wall.

is developing country, for using of remaining land efficiently, so some companies constructing high rise buildings. Many of countries for constructing buildings using steel structures but in our country steel structures rarely using due to lack of knowledge and economical reason. The improvement of tall structures relates various complex angles, for example, financial aspects, logical information, feel government strategies. The money related element will be the essential deciding variable. Tall structures request a ton of specialized support without which its development is unrealistic. As the tallness of the structure is expanded the horizontal supremacies following up on the structure additionally quickly increments. Subsequently the oblique load opposing frameworks goes out to be tremendously basic. Behavior of concrete, earthquake effect and design of earthquake resistance for different zones and different soil condition these are parameter commonly consider for construction activity. Earthquake is one of the natural phenomena it may happen due to naturally or human activity, what it may be it required safety of buildings to resist seismic loads. For analysis of structure, considering the zones, soil condition and other data will available in IS 1893-2000 code book. The diagrid frameworks empowered the current contemporary engineering as a development, blurring without end the customary propped arrangement of 1970s. The refinement between the diagrid structures and conventional propped frameworks is that for all intents and purposes all the run of the mill segments at the building blueprint are disposed of. The appropriation of diagonals components named as diagrid at the building blueprints is favorable basically and additionally stylishly. In diagrid structures, the meeting corner to corner components fundamentally works as a supporting framework rather than the vertical segments. This capacity of diagrids has made it conceivable to dispose of the border sections. The diagrids have favorable circumstances like lightweight structure, compelling against gravity stack, resistance against seismic and wind loads, excess, possible for contorted and other complex structures, reasonable. The slanting components of the diagrid framework shapes triangulated course of action in a uniform dispersal way which successfully convey both gravity load and parallel burdens.
